My understanding of the physics of the imagers is that you get much better
performance if you keep the imager dark until you take the image.  So the
image quality does depend on the shutter.  And by keeping the imager dark,
you don't have to reset it prior to capturing the image so you minimize
shutter lag.

Hi Karl,

It has to do with the sensor type, and interline sensors, that the cheapo
digicams use have an electronic shutter.

They have better image quality because the sensors are so much better, not
because they use a shutter!

I don't believe that has anything to do with the shutter, I believe it's the
sensor and camera design, shutter or not.

Please do ;-)
